However, there are a number of anime antagonists whose
modus operandi and skill sets are so down-to-earth that they could reasonably exist in the real world. Their practical applications of evil distinguish the fantastical villains from those who might be lurking just a block away.
The Yotsuba group was a coalition of powerful businessmen in the Death Note universe. Although successful in their own right, they struggled against competitors and sought a way to remove them. When Kira offered Kyosuke his notebook in exchange for his cooperation, the man was more than happy to agree.
